Holly nutgrass

I'm finally out able to fertilize my warm season grass. Mos is 75%+ greened up. We are about 2-3 weeks behind on green up due to weather.

Bad part is we are already seeing nutgrass and killinga. Enough of it that spot spraying is needed.

I haven't seen it this early in a very long time. I usually only have to treat for it in rd 3 and 4.

I've prided myself in treating "all" weeds at each round. I guess I should have stated in my program that 2 yearly mls sedge treatments are included. This 3rd treatment is going to be tough on the pocket.

Getting ready for call backs....

It the same in Oklahoma. We usually don't see it until much later in the summer, but it is coming on strong right now.

Most of the Bermuda is still not even to the point of needing to be cut yet!

What type of nutgrass wilson? On purple nutsedge, my best control comes from letting it all grow up, then hitting the entire lawn with a soil active herbicide. Yellow nutsedge can be gotten with Basagran or Dismiss. I use Dismiss for purple in combination with the slower acting products and as a split application.

It is normal for my rd-3 to include spot spraying of Nutsedge. My round 3 is fertilizer....and this helps pull down the product.
Yes, the sedge is crazy........and so is the yellow and green foxtail.
My early Spring Simazine apps didn't faze it, especially with all the cool and wet weather.

Mostly yellow and killinga. Been very wet here.

I usually spot treat with prosedge in rounds 3 and 4.

That stinks. Simazine does not do much to nutsedge. If there is too much rain, it goes past the root zone of the annual grasses and into the water table. For me, I keep simazine for the dry part of the year where the only water there is comes from the irrigation system. Which is calibrated to apply about an inch of water per week. Different from rain storms where you might get an inch of water per hour for the next 8 hours.

Those two weeds are controllable with Basagran. Prosedge does not do enough to kyllinga. I have had lawns that were a combination of purple and kyllinga convert to all kyllinga as a result of Prosedge. In warm season grasses, Certainty is a godsend. It kills both varieties of nutsedge and kills kyllinga. For me, Prosedge is still an expensive product, considering what it does not do for kyllinga. I wish the spectrum of sedges I have here were controllable with Basagran. $25 an acre is a lot better than the $100 per acre for the "sulfuron" sedge killers.
